From Iron Dog:
Attention Racers!! It’s official. Our GPS tracking will be conducted using a new device this year. Every sled will be required to mount a SPOT Trace. We’re testing units with a few riders right now. The brackets will be here in time to install at the Tech Inspection (Feb 8th).

Thank you so much for both of your most informative posts.
I hope you will be with us throughout the IRON DOG!
